I'm wondering if there is some convenient way to export multiple artboards as PNG/JPG files with different suffix by using one operation. For advertising purpose I often need to prepare one layout in completely different sizes with no common ratio between them. I found that the fastest way to create them is to make one separate artboard per size in one document.

But the convenience of that solution ends when I have to export 10-20 artboards this way -> title_WxH.png (where W and H stand for dimensions in px).

I wish I could assign particular suffix to each artboard, and then use such PSD file as a mockup for every product I have to prepare in the future.
